I appreciate it, I thought the 5260 cy was what they had initially
calculated at bid time.

Marty,
I spoke with the engineer earlier. He advises me that there was a bust
in the excavation quantity. They calculate the channel excavation at
5,260 cubic yards.
They are reviewing these calculations and will send me a memo with their
findings.
Keith

Keith,
We use Agtek to do our excavation takeoffs, it uses multiple cross
sections to calculate the quantities.
We would like to see what the engineers quantities were on both the
street and channel separately. As you can see, the channel itself is
more than the bid quantity which is what caught our attention when
tracking our completed quantities in house.

James,
I'm not sure I follow the method used to calculate this quantity. I
have forwarded it to the engineer for review.

In the event we agree that the quantity in the plans is significantly
less than the actual quantity, how does JRJ propose to reconcile the
situation? This excavation quantity is a "Plans Quantity" item, and as
such we can not simply over run it.

Keith,
We noticed that the qty of excavation was more then what was in the bid.
I have attached a takeoff on just the channel. The qty of excavation is
more than the bid qty. Again this is just the channel, when you add in
the qty of excavation for the roadway then the qty is even more off.
